Contoh Tujuan Pengajaran

Predict the necessary mass, velocity, and distance from the sun of a planet in order for this planet to make a circular orbit around a sun.

What happens when you increase or decrease the mass of the planet, but keep everything else constant? Does this agree with your prediction?

What happens to the orbit of the planet when you increase or decrease the magnitude of the velocity of the planet, but keep everything else constant?

What happens to the planet's orbit when the increase or decrease the initial distance between the planet and the sun?
